If the cutting insert to be moved radially, the L-shaped adjustment must be radially displaceable; In this case, the axial position of the respective cutting insert remains unchanged. Alternatively, an adjustment in the axial direction can be created in that the L-shaped adjustment device is longitudinally displaceable.

Abstract

L'invention concerne un outil comportant un porte-outil sensiblement cylindrique qui présente, sur sa face frontale, plusieurs évidements pour recevoir des inserts de coupe (12), ledit outil comprenant également un dispositif de réglage (13) pour déplacer un insert de coupe dans le sens radial ou axial. Selon l'invention, deux montants du dispositif de réglage présentant un contour en L, au moins sensiblement dans le sens transversal, sont appliqués contre l'insert de coupe qui a de préférence une forme sensiblement parallélépipédique, et le dispositif de réglage est mobile dans le sens radial ou axial au moyen d'une vis filetée (15) qui entraîne l'insert de coupe.
